'Ambush' in the Bible

Their tongues are deadly arrows—they speak deception.With his moutha man speaks peaceably with his friend,but inwardly he sets up an ambush.

Raise up a signal flagagainst the walls of Babylon;fortify the watch post;set the watchmen in place;prepare the ambush.For the Lord has both planned and accomplishedwhat He has threatenedagainst those who live in Babylon.
